This invention relates to advertising apparatus and especially to that type incorporating display curtains. 7

An object of this invention is to provide a simple, practicable and efficient apparatus for the display of a large number of individual advertisements either in a continuous motion or in intermittent stop periods.

A further object is to provide a machine of compact structure in which a number of endless display curtains are closely installed and provide for large capacity of various display panels without using a large base area or chamber space.

Other objects, advantages and features of construction and combination, and mode of operation will be made manifest in the ensuing description of the herewith illustrative embodiment; it being understood that modi- 20. fications, variations and adaptations may be resorted to within the spirit, scope and principle of the invention as it is more directly claimed hereinafter.

Figure 1 is a front elevation of the appa- 2 ratus.

Figure 2 is a vertical, central section front to rear of the apparatus.

Figure 3 is a detail of the driving drum of the mechanism.

Figure A is a vertical section from side to side, showing the display curtains and driving means in detail.

Figure 5 is a vertical section on line 5-5 of Fig. 4, showing arrangement of superdisposed curtains of the apparatus.

Figure 6 is a detail of connected ends of a display curtain.

The present machine is incorporated in a suitable housing or cabinet 2 having movable side wall doors 3 whereby to provide access to the mechanism and enable ready change of advertisement belts from time to time. The rear of the cabinet has doors 4.

A feature of this invention is the efiective driving of a plurality of endless curtains from a single drive belt 5 which passes over a top roller 6 and a bottom roller 7 disposed horizontally just in rear of the windowed front 8 of the cabinet. From the bottom roller 7 the belt passes up to a driving drum from .A and on it is draped an endless curtain 20 1929. Serial No. 373,224.

- drum shaft 10, or the drum, isprovided with cams 17 operative to engage arms of a yoke, 18 pivoted at 19 and having links 20 in which the tension roller 12 iscarried. When the cams 17 actto lift the roller 12 lack of friction causes the drum 10 to revolve without Inovingthe belt which dwells'until the cams again releasethe yoke and lower'the roller to tensioning position in. belt bight 11.

In the present disclosure. the front 8 has a central window A and flanking. windows. BFB, and CC.. v i

The belt 5 is about as wide as the window whichis. about as wide as window A and loops in front of rollers '67 and lies close to the front 8 and passes back of the drum 10. The weight of the centralcurtain 20 causes it to travel with its supporting belt 5 as thisv is driven.

The top roller 6 is secured on its shaft 6 and to the ends of this are applied extension rollers 6 and 6 which carry draped endless curtains 20 and 20 registering withthe windows B andC. Thelower bights of the curtains 20 -20 are deflected rearward in the. cabinet and carry tension rollers 20 to keep them taut on their drive drums or rollers.

The supplemental drum 13 is secured on shaft 13 and to the ends of this are applied extension drums 13 and 13 on whichhaug endless curtains 21 and 21 which register with windows B C and lie in front of the lower'bights of the curtains 20 20. The curtains 21"21 have tension rollers 22. The front planes of all the curtains are substantially coplanar and lie close to the front windows so that panels X of advertising media are clearly visible, in succession during operation of the machine.

It will be seen that the belt 5 drives the shafts 6 and 13' and these drive the drums carrying the lateral curtains 20, 20, 21 and 21. To change the lateral curtains it is only necessary to-slide them edgewise ofi' their drive rollers. The central curtains 20 may have separable meeting ends attached by any suitable fastening, Fig. 6. The display part of the curtains20 20 are relatively superdisposed as is clearly seen in Fig. 5; the upper curtains deflecting back over guides 28-29 to clear th drums 13 13.
